Jack and Jill bathrooms get their name from the popular children’s nursery rhyme about two siblings. These bathrooms are directly accessible from two bedrooms and were originally designed to be shared by siblings, hence the name. The term is catchy and so it has never been replaced.

When I first heard the term “Jack and Jill bathroom”, I had no idea what it meant; surely a bathroom is just a bathroom, right? Well, I was wrong, and I don’t mind admitting it. There are actually several different types of bathroom designs that are used in homes all over the world. These unique bathroom types are designed to meet a specific purpose or perform a specific function. One such bathroom is the Jack and Jill bathroom.

Jack and Jill bathrooms are growing in popularity, and many are considering using them in new home developments. Let’s further explore the Jack and Jill bathroom, and identify some of the pros and cons of this design, and discover some of the unique features of this bathroom design.

What Is a Jack and Jill Bathroom?

A Jack and Jill bathroom is a unique bathroom design. This type of bathroom is situated between two bedrooms and has a door into the bathroom from each room.

Some Jack and Jill bathrooms have a third door leading to a hallway, although this does alter the design.

A Jack and Jill is effectively a shared ensuite bathroom for two bedrooms. These bathrooms are meant to be used by two siblings, which reduces bathroom limitations for big families.

These bathrooms often feature a double sink (often with separate storage attached to each sink) and all the amenities of a full bathroom, including a bath, a shower, and a toilet.

While this design is intended for siblings, it could be used by any two people, so long as they are willing to share a bathroom.

Privacy in Jack and Jill bathroom is ensured by installing internal locks on all doors, allowing any occupant to keep others from entering the bathroom unexpectedly.

“Jack and Jill Went up the Hill”

These bathrooms are more common than you may expect, but why were they given such a unique name?

The Jack and Jill bathroom style is so-called because it is intended for use by siblings. The name is based on the popular children’s nursery rhyme written about two siblings, Jack and Jill, who went up the hill.

This name has prevailed due to the nursery rhyme that it is based on and the fact that it is a catchy and iconic bathroom style. This bathroom style is featured in several popular media appearances, such as The Brady Bunch, which has helped etch the name into bathroom design history.

Variation of the Jack and Jill Bathroom

The Jack and Jill bathroom design is fairly commonly used internationally. There are some variations of the design, but the only true Jack and Jill design is a bathroom that is between two bedrooms with an entrance each, and with no hallway door.

Some designs that are commonly called Jack and Jill bathrooms are any bathrooms that have double facilities such as a double sink and a shared bathroom that opens into multiple rooms.

However, these designs are not considered to be true Jack and Jill bathrooms.

Pros and Cons of Jack and Jill Bathrooms

Jack and Jill bathrooms are designed for the specific purpose of use by siblings or two members of the same household. These bathrooms are connected only to two bedrooms and allow the occupants of both rooms private access to the bathroom.

This type of bathroom is very convenient in some ways, but there are some drawbacks to the Jack and Jill design.

Let’s discuss some of the pros and cons of Jack and Jill bathrooms:

Pros of Jack and Jill Bathrooms

  • Jack and Jill bathrooms save a significant amount of space.
  • Building one bathroom instead of two reduces costs.
  • Jack and Jill bathrooms offer more privacy than other bathrooms, as they can only be accessed by two people in the house.
  • Jack and Jill bathrooms offer more internal space than regular bathrooms.
  • Dual amenities in these bathrooms, such as two sinks, are very convenient.
  • A Jack and Jill bathroom can be customized to suit the needs of those using it, rather than just being a general bathroom.
  • These bathrooms can be decorated and painted according to the taste of those who use them, rather than looking like a generic bathroom.

Differences Between His and Hers and Jack and Jill

Jack and Jill bathrooms are uniquely designed for the use of two people, usually siblings, who reside in different rooms but share one bathroom. This design is not to be confused with other types of shared bathroom designs.

Many consider a couple’s bathroom to be Jack and Jill bathroom, but these bathrooms are known as His and Hers bathrooms.

Jack and Jill bathrooms are usually shared by two siblings, while His and Hers bathrooms are designed for use by a couple. 

His and Hers bathrooms are equipped with features that are not present in Jack and Jill bathrooms. His and Hers bathrooms are designed to be used by a couple and allow for portions of the bathroom to be used simultaneously. 

Some distinguishing features of His and Hers bathrooms include:

  • A two-person shower, large enough for two people to shower simultaneously.
  • A separate toilet room, allowing one person to use the other sections of the bathroom while the toilet is occupied.
  • A double basin designed for a couple, with unique sides for each person.
  • His and Hers bathrooms often have neutral colors, which is common ground between the taste in the style of both persons using the bathroom. 
  • Ample storage—enough for the use of two people.

Differences Between Unisex and Jack and Jill

There is a misconception that the term Jack and Jill refers to a unisex bathroom when the truth is that a unisex bathroom is a different design altogether.

A unisex bathroom is a bathroom that is designed to cater to both men and women, but these bathrooms do not usually have features that are present in other types of shared bathrooms such as Jack and Jill and His and Hers bathrooms. 

Unisex bathrooms typically have only one set of amenities, rather than employing the use of double sinks and larger showers. 

These bathrooms can be used by either gender without catering specifically to one group or the other; men and women should have no problem using a unisex bathroom.

A bathroom of this type is not necessarily a shared bathroom; it is simply a bathroom that caters to everyone and can be installed in any home for the use of all occupants.
